Abstract— As the software radio makes its transition from
research to practice, it becomes increasingly important to establish
provable properties of the software radio architecture
on which product developers and service providers can base
technology insertion decisions. Establishing provable properties
requires a mathematical perspective on the software radio architecture.
This paper contributes to that perspective by critically
reviewing the fundamental concept of the software radio, using
mathematical models to characterize this rapidly emerging technology
in the context of similar technologies like programmable
digital radios. The software radio delivers dynamically defined
services through programmable processing capacity that has the
mathematical structure of the Turing machine. The bounded
recursive functions, a subset of the total recursive functions, are
shown to be the largest class of Turing-computable functions
for which software radios exhibit provable stability in plug-andplay
scenarios. Understanding the topological properties of the
software radio architecture promotes plug-and-play applications
and cost-effective reuse. Analysis of these topological properties
yields a layered distributed virtual machine reference model
and a set of architecture design principles for the software
radio. These criteria may be useful in defining interfaces among
hardware, middleware, and higher level software components
that are needed for cost-effective software reuse.
